I Need an Advanced Automation Developer – Redirect-Based Booking Bot (Goethe, Wicket Apache, COE Session Handling) For Goethe Booking like Chennai and Bangalore I am looking for a high-level automation/bot developer who has experience with: Wicket/Apache-based web applications Multi-step redirect chains COE session initialization & dynamic token handling ColdFusion (CFID/CFTOKEN) & JSESSIONID flows Cookie extraction & accurate replay of Set-Cookie across redirects Chrome CDP automation / Playwright / Puppeteer High-speed DOM watching (DOMWatcher / MutationObserver) Proxy rotation & session isolation --- Project Goal Build a bot that can open the “Select Modules / Book” page reliably during Goethe exam seat drops, even when: normal browser attempt shows "We are sorry, high demand…" the booking button is visible only for milliseconds the server uses strict Wicket state, session validation, redirect pruning, and timing-based acceptance The bot must reproduce: the exact Chrome behavior, the correct redirect chain starting from the button link, and all intermediate cookies and server state parameters. --- Key Technical Requirements 1. Reproduce full redirect chain From the button link: [login to view URL] The bot must follow all server redirects accurately: /coe?lang=… /coe/?lang=… /entry?lang=…&oid=… /selection?... Final page that shows available modules. 2. Correct handling of all dynamic cookies The bot must automatically extract and reuse: coesessionid COE-Tab-ID COE-Customer CFID / CFTOKEN JSESSIONID SRVCMS5WWW Missing any of these breaks the chain. 3. Accurate reproduction of Chrome headers Including: sec-ch-ua sec-fetch-* Referer Origin Chrome TLS/HTTP2 behavior (via CDP, not simple requests) 4. DOM watcher for instant-click The bot must: run 20–40 parallel isolated sessions detect the green “SELECT MODULES” button in <5 ms click instantly and open the booking page in a real Chrome window 5. Proxy + Session Isolation Each tab/session must run with: separate cookies separate profiles optional proxy separate localStorage separate COE-Tab-ID --- Expected Deliverables 1. Backend module: performs all redirect handling extracts & reconstructs session cookies verifies valid coesessionid 2. Frontend module: opens real Chrome instance loads booking page using backend-generated session triggers instant click shows the booking flow normally for manual payment. 3. Configuration panel (optional) add accounts choose city, exam, time set number of parallel tabs “If my current approach is incorrect, I would like to understand the correct method to handle this system. If you have the expertise, please guide me or help me build a fully functional bot script.” Skills Required Playwright / Puppeteer / Selenium (CDP mode) Strong understanding of HTTP/2, redirects, cookies, CSRF Experience with anti-bot bypasses Experience with Wicket / Java server-side frameworks --- Only Experienced Developers This is not a simple Selenium clicker job. Only message if you have real experience with strict session-based booking systems. Provide: past work samples your approach to solving redirect-based session recreation estimated timeline & cost --- Contact Message me here on Freelancer with: “I understand the Wicket redirect chain” and your past automation experience.

As an experienced Automation Developer, I have successfully built bots for complex booking systems like Goethe, using advanced technologies such as Wicket and Apache. In addition, I have a deep understanding of cookies, redirects, proxy rotation, and COE session initialization - all of which align perfectly with your project requirements. My expertise in manipulating cookies and accurately replaying Set-Cookie across redirects has proven valuable in automating multi-step processes. Furthermore, I also have hands-on experience in Chrome CDP automation / Playwright / Puppeteer aiding the high-speed DOM watching. Finally, my approach is simple yet effective: leverage state-of-the-art technologies while staying grounded and attentive to every specific demand of yours. I've successfully implemented parallel isolated sessions that detect buttons instantly for over 20 simultaneous tasks in real time. With my team of 20+ Professional Developers and Designers, all of whom are highly skilled and proficient in areas including (but not limited to) Mobile & Web Development, Website Design & Graphic Designing, I can reaffirm you that we have both the capability and competency to meet your project's high expectations making use of tools like Selenium, Puppeteer or Playwright among others.

I understand the Wicket redirect chain. I’ve worked extensively with redirect-heavy, state-dependent booking systems where the server enforces strict session validation, multi-token handoffs, and millisecond-level timing. Your Goethe COE flow aligns closely with projects I’ve previously built for exam portals, immigration slots, and ticketing systems where Wicket/Apache, dynamic cookies, and ColdFusion token pairs (CFID/CFTOKEN) must be replayed precisely to pass each redirect. **My Approach** **1. Full Redirect & Session Reconstruction** I replicate the exact Chrome behavior using Chrome DevTools Protocol (CDP). Each redirect is captured with its full request/response headers, Set-Cookie instructions, and intermediate tokens. I rebuild the chain programmatically by injecting: * coesessionid * COE-Tab-ID * COE-Customer * CFID/CFTOKEN * JSESSIONID * SRVCMS5WWW Missing or mis-ordered cookies are automatically corrected before the next redirect. **2. Chrome-Accurate Header & TLS Behavior** I replay all Chrome-native headers (sec-ch-ua, sec-fetch-*, Referer, Origin) and maintain HTTP/2 state so the server sees a true Chrome client and not a script. This prevents early rejection at the Wicket state check. **3. High-Speed DOM Watcher + Parallel Sessions** **4. Backend + Frontend Split** Backend handles all redirects, cookies, and session recreation. Frontend opens a real Chrome window using the validated session so the booking flow loads normally for manual completion.

Hi, how are you doing? I have solid hands-on work with complex redirect chains, cookie and session handling, and headless Chrome control using Playwright/Puppeteer in multi-tab setups with proxy isolation and real browser behavior. I’ve built automation for high-speed DOM watching and precise timing on dynamic pages, plus managing COE-like session tokens securely. I can share relevant past work, outline a practical approach, and estimate timelines and costs. Let me know if you’d like to discuss details.

Hi there! This is exactly the type of complex automation challenge I love to work on. From mastering tricky redirect chains and advanced session handling to reproducing real browser behavior with Playwright or Puppeteer, your requirements align with my expertise. I’m confident in building a robust bot that will flawlessly follow every redirect, handle every dynamic cookie, and instantly react to that fleeting “SELECT MODULES” button—all while ensuring session isolation and proxy support. I can break down my approach for you, demonstrate solutions to handle Wicket’s intricate stateful redirects and server-side validations, and show you how I’ll maintain a true-to-Chrome browsing context down to TLS details and HTTP headers. My top priority is making the booking process reliable, fast, and undetectable, with a modular backend/frontend plus optional configuration panel for total flexibility. If you’d like, I’m happy to review your current approach or propose a full workflow for a guaranteed, high-speed booking bot. Let’s connect so I can share relevant project examples, my technical roadmap, and a transparent quote. Looking forward to making this happen for you! Best regards, Vitalii

Hi there! I understand the Wicket redirect chain, and your project is exactly the kind of advanced automation challenge I excel at. I’ve previously built robust booking bots for high-demand systems using Playwright, Puppeteer, and direct Chrome DevTools Protocol automation. My past work includes solving strict session/cookie handling, multi-layer redirect chains, and DOM race conditions—especially for tricky platforms with fast-disappearing buttons and sophisticated server-side validation. For similar projects, I successfully reverse-engineered session flows and headers, handled dynamic cookie management (CFID, JSESSIONID, etc.), and ensured exact Chrome fingerprinting. I have designed bots capable of instant DOM triggers with MutationObserver and isolated up to 40 parallel browser sessions with proxy and storage separation. Your requirements for both backend (redirect/session/cookie logic) and frontend (real browser, instant click) modules match my skillset perfectly. I’ll provide a detailed approach and relevant automation samples, ensuring a transparent and efficient path to your goal. Looking forward to helping you outsmart the toughest booking flows! Best regards, Oleksandr
